The GetAvailable method retrieves the range of times in which seeking is efficient.
HRESULT GetAvailable( LONGLONG *pEarliest, LONGLONG *pLatest );
[out] Pointer to a variable that receives the earliest time for efficient seeking.
[out] Pointer to a variable that receives the latest time for efficient seeking.
Returns an HRESULT value. Possible values include the following.
|E_NOTIMPL||Method is not supported.|
|E_POINTER||NULL pointer argument.|
This method is intended primarily for seeking in media streams that might have excessive latency, such as streams being sent over a network. The returned values indicate cached data that has already arrived, which can be easily seeked. It is assumed that seeking to values beyond these returned parameters will cause a delay while the application waits for the data to arrive.
All time values are expressed in the current time format. The default time format is REFERENCE_TIME units (100 nanoseconds). To change time formats, use the IMediaSeeking::SetTimeFormat method.
